Package Exports

json-atom

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (json-atom) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

json-atom

    const {get, set, apply} = require('json-atom');
    const data = {
        user: {
            contact: {
                home: {
                    number: 11111
                }, mobile: {
                    number: 22222
                }
            },
            posts: [
                {content: 'Hello World!', likes: 10},
                {content: 'Goodbye World!', likes: 1}
            ]
        }
    };

    let result = get('$.user.contact.home.number')(data);
    // 11111

    result = get('$.user.contact["home","mobile"].number')(data);
    // {home: 11111, mobile: 22222}

    result = set('$.user.contact["home","mobile"].number')(99999)(data)

    // set is Immutable, data hasn't been modified, a new refernece is returned
    // lenses powering json-atom effectively behave like HAMT
    // They only create new objects for the nodes from root to path, the rest of the structure is shared.

    // {"user":{"contact":{"home":{"number":99999},"mobile":{"number":99999}},"posts":[{"content":"Hello World!","likes":10},{"content":"Goodbye World!","likes":1}]}}

    // number fields under both branches, namely 'home' AND 'mobile' are both set to value in the new object reference

Build Targets

Currently the following target build environments are configured for babel-preset-env plugin

 "targets": {
   "node": 4.3,
   "browsers": ["last 10 versions", "ie >= 7"]
 }

In case this turns out to be not generous enough, more backward compatible babel transpilation targets would be added.
